Subject: [PATCH] drm/amd/display: return status of abm_feature_support
Date: Thu, 20 Apr 2023 09:21:29 -0400 [thread overview]
Message-ID: <20230420132129.3888917-1-trix@redhat.com> (raw)
gcc with W=1 reports
drivers/gpu/drm/amd/amdgpu/../display/dc/dce/dmub_abm.c:
In function ‘dmub_abm_set_event_ex’:
drivers/gpu/drm/amd/amdgpu/../display/dc/dce/dmub_abm.c:138:22: error: variable
‘feature_support’ set but not used [-Werror=unused-but-set-variable]
138 | unsigned int feature_support;
| ^~~~~~~~~~~~~~~
This variable is not used so remove it.
The status of amb_feature_support should have been returned, so
set ret and return it.
Fixes: b8fe56375f78 ("drm/amd/display: Refactor ABM feature")
